Not sure if you're ready to replace your windows?
For a full window replacement, the most common frame materials are vinyl, fiberglass, wood, and composite. Within each, you choose the style, double-hung and casement being the most common, and the glass package that suits your climate. Many homeowners bundle window replacement and door replacement, since both are handled by the same crews.
Repairing a window makes sense for a failed seal, damaged hardware, or a single broken pane on a unit that is otherwise sound. Replacing the whole window is usually the better call once several units are drafty, fogged, or painted shut.

Installed cost in Baltimore runs within about a percentage point of the national average for this trade. Here's how we got to that number.
Project costs include three main components: labor, materials, and overhead. Material ships at national prices no matter where you live, and overhead is fairly consistent as well. So the main pricing difference between metro areas is labor costs. This is why a quote from a high-wage metro is rarely as far above the national average as people expect.
To get Baltimore labor costs, we compared the average hourly wage in the Baltimore-Columbia-Towson, MD area to the national average hourly wage for this trade. (source: US Bureau of Labor Statistics, Occupational Employment and Wage Statistics, May 2025)
We found that the local trade wages are close to the national figure. Labor costs typically make up about 26% of a window replacement project cost, so the weighted difference between Baltimore and national averages is under 1%. See methodology and sources.
It depends on the scope of your project, so you should talk to the permitting authority to find out what your project needs. In general, Baltimore permitting is moderately complex compared to other metros we cover.
Permitting for most structural and plumbing goes through Baltimore City and surrounding counties. Historic preservation requirements apply in many Baltimore neighborhoods.
You should ask each contractor if they pull the permits for you and if the fee for pulling permits is included in their quote. Also, tell them you need to see the written, approved permit before work starts.
Maryland requires window replacement contractors to register with the state, which is not the same as holding a license. (source, verified as of 2026-08-12) What that means and how to verify a contractor in Maryland →

Renewal by Andersen is consistently reviewed as a premium replacement window provider known for custom-built windows, professional installation, and a simple, hassle-free process from start to finish. Homeowners frequently praise the overall installation experience, noting that crews were professional, friendly and detail oriented. While the investment is often higher than some alternatives, many reviewers mention the customized fit, quality of the finished product, and professional service as reasons they feel the investment is worthwhile.
Home Genius Exteriors holds Owens Corning Platinum Preferred status alongside James Hardie Elite Preferred and CertainTeed 5-Star contractor certifications, and covers roofing, siding, windows, doors, gutters and attic insulation. Reviewers name their project manager more often than almost anything else about the job, and describe them staying involved and checking in through to the finish. Siding and gutter work draws the warmest praise for how it looks once finished, and most installs wrap up in just a few days. Their free inspection is thorough and photo-led, with some homeowners noting drone footage of the roof itself. Promotional discounts are tiered by trade rather than applying across the board, so ask what your specific project qualifies for. If your roof is flat or low-slope, ask what warranty comes with it, since those systems are covered differently.
Window Nation’s reviews are consistent about the sales visit: homeowners describe a consultant who lays out window options and pricing plainly, without pushing for a decision on the spot, and they often name that person specifically. Several branches carry their own “no-pressure sales” tag in the review data, and the price itself draws steady praise, especially from homeowners who compared it against other quotes first. The install crews get the same kind of specific praise. Reviewers describe crews arriving on time, often early, protecting floors and furniture, and finishing a whole house of windows in a single day before hauling the old ones away. Window Nation fits its own exclusive Soft-Lite line, the Envision series, and every unit passes a 50-point factory inspection before it ships. The limited lifetime warranty transfers if you sell your home, though the request has to go in within 60 days of closing and carries a fee. It is worth asking about that at the consultation, along with how quickly a service call gets scheduled if you ever need one.
Victory Home Remodeling covers windows, roofing, siding and gutters across the Northeast and Mid-Atlantic (New Jersey, New York, Pennsylvania, Delaware and Maryland), installing and warranting house-branded systems supplied by established manufacturers: EnduranceX™ siding from Norandex, roofing materials from GAF. It is a GAF Master Elite contractor, a designation held by only about 2% of roofers nationwide. The process runs through a named salesperson and project manager, with a quality inspection at the end rather than a single handoff, and reviewers consistently describe the installation crews as clean, careful with the house, and quick to finish on the date first promised. Its warranty is genuinely one of the stronger ones in this category: lifetime, non-prorated on both labor and product, transferable once to the next owner, and it covers glass breakage regardless of cause. Get the full scope, including trim, siding tie-ins, and what the warranty covers, in writing before the crew starts.
